How efficient is the Laars Pennant?

The Laars Pennant operates at 88% AFUE (Annual Fuel Utilization Efficiency), meaning 88% of the fuel it consumes is converted directly into heat for your home. This provides reliable heating at a solid efficiency level for cast iron construction.

How much does the Laars Pennant cost to install?

The Laars Pennant typically costs $3,500 - $6,500 for a complete installation in Nassau County, NY. This includes the boiler unit, professional installation by NATE-certified technicians, permits, and a standard warranty. Actual costs may vary based on your home's specific requirements, piping condition, and any necessary modifications.

Is the Laars Pennant worth it?

With 88% AFUE efficiency, you can expect to save approximately $127 annually compared to an 80% efficient boiler. Key features like Steel fire-tube design and Pool and spa compatible make it a compelling choice. It's particularly well-suited for homes with pools needing combined heating solution.

What is the warranty on the Laars Pennant?

Laars provides a 5 years parts warranty and 10 years on the heat exchanger. For the best warranty protection, we recommend registering your boiler within 60 days of installation. Our installations include a workmanship guarantee on top of the manufacturer warranty.

How long does the Laars Pennant last?

With proper maintenance, the Laars Pennant should last 15-25 years or more. We recommend annual tune-ups to maximize lifespan and maintain peak efficiency.

Does the Laars Pennant qualify for PSEG Long Island rebates?

The Laars Pennant at 88% AFUE doesn't currently qualify for PSEG efficiency rebates, which typically require 90%+ AFUE. However, its proven reliability and lower upfront cost may be the right choice for your home.

Expert Review: Laars Pennant

The Laars Pennant delivers solid 88% AFUE efficiency in a traditional cast iron package, representing reliable mid-tier performance for Nassau County homes with hot water baseboard heating systems.

Laars' long manufacturing heritage provides confidence in component quality and parts availability. Our installation teams have serviced Pennant boilers across decades of operation, confirming the platform's durability in Long Island applications.

For homes in Hicksville, Westbury, and the surrounding communities with existing baseboard systems, the Pennant provides straightforward replacement without system modifications. The cast iron heat exchanger handles the thermal demands of Long Island winters while resisting the wear of seasonal cycling.

Bradford White's acquisition of Laars strengthens the brand's manufacturing and support resources. Local distributors like F.W. Webb and Sid Harvey's stock Pennant parts, ensuring rapid service when needed.

The Pennant's atmospheric burner design provides reliable ignition in basement installations, and the boiler's accessible components simplify annual maintenance.

Value proposition: The Pennant represents an excellent choice for homeowners prioritizing proven cast iron reliability at mid-tier pricing, particularly in applications where condensing technology's premium isn't justified.
